GUSTAF SANDELL, OF BROOKLYN, ASSIGNOR TO THE EAGLE PENCIL COMPANY, OF NEV YORK, N. Y.

HOLDER FOR CRAYONS, SLO.

SPECIFICATION forming part of Letters Patent No. 432,570, dated July 22, 1890.

Application tiled February 24, 1890. Serial No. 341,509. (No model.)

T all whom, it 11i/ay concern:

Be it known that l, GUSTAF SANDELL,-of Brooklyn, New York, have invented certain new and useful Improvements in Holders for Crayons, Pencil-Leads, ttc., of which the following is a speciicat-ion.

My invention is an improvement upon that type of lead and crayon holder conveniently termed a gravity-holder, in which the lead is automatically projected from the sheath and locked in that position whenever and so long as the pencil is held point downward, the lead being correspondingly released and allowed to drop back within thev sheath when the pencil is turned point upward. A pencil or holder of this type is not new with me, nor is it broadly claimed by me.

My invention consists of certain specific improvements upon this kind of holders, which can best be explained by reference to the accompanying drawings, in which- Figures l and 2 are longitudinal sectional elevations of the holder, point upward and downward, respectively. Fig. 3 is a view of the follower detached. Figs. 4, 5, and 6 are views of the gravity mechanism of the pencil, which, in connection with Figs. l and 2, serve to illustrate the action of the parts. Fig. 7 is a sectional view illustrative of the propeller mechanism for the pencil-lead, by which it may be adj usted in its carrier or holder proper.

The pencil shown in the drawings consists, generally speaking, ot' a sheath or tubular handle A, a slotted` guide-tube B, held stationary in the sheath, a lead-carrier C, contained in the stationary guide-tube and mov-v able by gravity lengthwise therein within lixed limits, and a follower-tube or lockingtube D, contained loosely within the guidetube and loosely encircling the lead-carrier. In the guide-tube is the longitudinal slot a, terminating at therear in a lateral recess or notch a on one side of the slot, and at the front in a lateral recess or notch a2 on the other side of the slot. The followerD is provided with a stud d, and the lead-carrier C is provided with a stud c. Both of these studs enter the slot a of the stationary guide-tube, the stud'c of the carrier projecting,` into said slot a through a longitudinal slot b in the follower D. The rear notch a is only for the stud d of the follower. The front notch a2 is only for the stud c of the carrier. The range of movement of the carrier C is sufficient to permit the pencil-point to be projected from or retracted within the sheath, according as the pencil is held point downward or point upward. Its extent of movement, in the present instance, is from the rear end of slot b (when the follower has dropped back to its rearmost position, as in Fig. l) to the front end of the slot a, in the guide-tube.

Vhen the pencil is point upward, the parts are in the position shown in Eig. l, the stud d of the follower being in the rear notch a of the guide-tube, and the stud c of the carrier being in the slot a, resting on the shoulder at the rear end of slot b in the follower. lf now the pencil beturned point downward, the carrier O by gravity will drop, its stud ctraveling down slot a of the guide-tube and holding the follower-stud d in the notch a', as seen in Fig. Il. The parts maintain this position until the carrier-stud c reaches the front end of the guide-slot a, and during this time the follower remainsV motionless in its eXtreme rearwardposition,with its stud d in the rear notch a. lVhen the carrier-stud reaches the front end of the slot a, it meets at this point an incline ai, which diverts or turns it into the front notch d2. By this movement of partial rotation of the carrie-r the stud c is caused to impart a slight rotary movement to the follower D, sufficient to bring its stud d out of the rear notch a and in line with slot a, as seenin Fig. 5. The follower, being now free to move, drops down until the rear end of its slot b brings up against the carrier-stud c, as seen in Fig. 2, and the carreris thus locked in its pro truded position. To return the parts from the position shown in Fig. 2 to that shown in Fig. l, the pencil is turned point upward. lower drops back, the carrier meanwhile, as seen in Eig. G, remaining at rest until the follower reaches its rearmost position and the follower-stud turns into its notch a2, thus permitting the release of the carrier, whose stud c is brought in line with the main slot a, the carrier thereupon dropping back to the The foly IOO position shown Ain Fig. l. Thus itwill be seen that the carrier and follower are capable each of a movement of partial rotation with reference to the guide-tube B; that during this rotating movement they lnove together; that they are capable of independent longitudinal movement with relation both to each other and to the guide-tube; that duringthc longitudinal movement of the earrier the follower is not so moving, and vice versa, and that so long as the carrier-stud is in the slot (t the follower is locked in its rearmost position, and, on the other hand,so long as the follower-stud is in the slot a the carrier is locked in its foremost position.

The carrier may be of any suitable construction. The particular one shown on the drawings embodies the movement of the well-known propelling and repelling pencil, consisting of an internally-screw threaded exterior tube a', an interior longitudinallyslotted tube y, swivelcd in tube :1f/,so as to rotate therein without longitudinal movement, and a sliding pencil socket or holde within the swiveled slotted tube m, provided with a pin or stud 1, which projects through the slot in tube g/ and engages the screw-thread of tube 51;. The swiveled tube y is provided with a tip or nozzle y', which projects to the front beyond the tube at. The pin c prevents thc latter (tube ir) from turning when the tip y is taken hold of and rotated for the purpose of adjusting the lead.

Having thus described my improvements, I state, in eonclusiomthat I donot claim apencil-casing having a longitudinal aperture, a lead-holder freely movable by gravity longitudinally within said aperture, and a lock wit-hin the easing movable longitudinally an d operated by gravity, and which engages with the lead-holder and locks it while the pencil is in use. Nor do I claim the combination of the casing or sheath, the gravity-carrier freely movable therein within prescribed limits, and the gravity-follower separate from the carrier and freely movable in the sheath independently of the carrier and operating to lock the carrier in or release it from its advanced position, according as the holder is held point downward or upward. I also remark that I am aware that a gravity-holder has been made and patented in which the carrier is combined with a propelling device or follower operating on the carrier pin or stud by gravity to move said carrier along and impart to it a partial rotation in iheguide-tube.

In the structure which I have invented the follower has no such function. It is only after the carrier has moved forward to its full extent and. has of itself turned so as to bring its pin or stud into its locking-notch that the follower begins its longitudinal movement. That movement does not move the carrier along, nor does'it rotate the carrier, because both of these movements have already been accomplished, and the sole function of the follower under these conditions is to lock the carrier in a position which it assumed of itself before the follower commenced its forward movement.

lVhat I claim, and desire to secure by Iletters Patent, is

l. A holder for crayons, pencilleads, and the like, comprising, in combination, the sheath A, the stationary slotted guide-tube l i, provided with a rear notch extending from one side of the slot and a front notch extending from the opposite side of the slot, the tubular longitudinally-slotted follower l), loosely contained in the guide-tube, so as to be capa ble of longitudinal and rotary movement therein, and provided with a stud to enter the slot a of the guide-tube and to engage or enter the rear notch a', and the carrier t), loosely received in said follower and provided with a stud which extends through the slot in the follower into the slot a in the guide-tube and is adapted to enter and engage the front notch a2, as and for the' purposes hereinbefore set forth.

2. The combination, with the sheath and the stationary slotted guide-tube provided with front and rear oppositely-placed notches or lateral recesses,of the follower and the carrier engaging one another and the guide-tube, substantially in the manner described, whereby, while having' a niovementof partial rotation silnultaiieously and together for the purpose of effecting the release of one or the other from locking engagement with the guide-tube, they shall move longitudinally dissiniultancously and successively, the one beingr locked against longitudinal movement unt-il the other has completed such movement, substantially as and for thepurposes hcreinbefore set forth.

In testimonyv whereof I have hereunto set my hand this 19th day of February, 1890.

GUSlAF SANDELL.
